SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 673,498, dated May '7, 1901.

Application filed November 1'7, 1900. Serial No. 36,874. (No model.)

To all whom, t puny concern;

Be it known that I, GEORGE W. DURANT, a citizen of the United States, residing at Alvin, in the county of Br'azoria and State of Texas, have invented a new and useful Sash- Fastener, of which the following is a specilication.

The invention relates to improvements in sash-fasteners.

One object of the present invention is to improve the construction of sash-fasteners and to provide a simple and comparatively inexpensive device adapted to hold the sashes' of a window at the desired adjustment and capable of firmly locking the lower sash.

Another object of the invention is to provide a device of this character in which the means for holding the lower sash in its closed position will be adapted to form loops for holding the curtains of a window.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is an elevation of a window provided with a sash holder and fastener constructed in accordance with this invention, the upper sash being partly open. Fig. 2 is a similar view, the upper sash being closed and the lower sash being locked. Fig. 3 is a vertical sectional view. Fig. 4 is a horizontal sectional View.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 and 2 designate the upper and lower sashes of a window, and the upper sash is connectedv between its ends by suitable fastening devices 3 with the lower terminals of coiled springs 4, which are adapted to support the upper sash and hold the same firmly in its closed position, and the said springs 4:, which are secured at their upper ends to the top of the window, are designed to be of a size and strength to connterbalance both the upper and lower sashes, so that when the two sashes are connected together, as hereinafter explained, they may be readily raised and lowered and will be supported at any adjustment. The coiled springs, which are disposed vertically, are housed within tubular casings 5, located at opposite sides of the eX- terior of the window and provided with vertical slots 6 and having vertical anges '7. The slots 6, which are arranged at the inner sides of the tubular casings, are located adjacent to the upper sash and receive the projecting fastening devices 3. The flanges 7 extend laterally from the tubular casings, at the outer sides thereof, and are disposed longitudinally of the window-frame, to which they are secured by suitable fastening devices. When the upper sash is raised and lowered,` the fastening devices 3, which extend outward from the said sash, move up and down in the vertical slots or openings of the tubular casings. The vertical flanges '7 are arranged midway between the inner and outer sides of the tubular casings,which have their upper ends located beneath the top of the window-frame to house and protect them from the weather.

The upper sash is provided at its inner face with a cord 8 or other flexible connection, which is secured to the top of the upper sash, and it is provided at its lower end with a ring 0r loop 10, adapted to engage any one of a series of hooks or projections 1l, arranged at different elevations on one side of the window-frame, whereby the upper sash may be secured at any desired adjustment and will be held against upward movement by the coiled spring, which will operate to automatically raise the sash 1 as soon as ythe same is released.

The lower sash is provid ed with a centrallyarranged series of knobs or buttons 12,'disposed atintervals at diderent elevations and `adapted to be engaged by a ring or loop 13 of a cord 14 or other flexible connection, which extends downward from the top of the window-frame, at which point it is secured to the-said frame. The ring or loop 13 of the cord 14 is adapted to be engaged with any one of the knobs or projections to hold the lower sash in an elevated position. The cord or connection of the upper sash is adapted also to be connected with the knobs or buttons of the lower sash to connect both of the sashes and subject the coiled springs to the weight of the two sashes. When the coiled springs are subjected to the weight of both sashes, the latter will be counterbalanced IOO and may be readily raised and lowered, and they will be supported in their adjusted position by the springs.

It will be seen that the sash fastener and holder is exceedingly simple and inexpensive in construction, that it is adapted to be readily applied to aWindoW, and that it Will hold the saches at the desired adjustment and will counterbalance the same and lock the lower sash firmly in its closed position.

Another advantage of the invention is that the vertically-disposed tubular casings, which are arranged on the exteriorof the Window, at opposite sides thereof, form efficient Weatherstrips and eiectuallyexclude air at the sides of the Window. The arrangement of the laterally-extending iianges also enables the tnbular casings to form efficient weather-strips, as the said flanges are secured to the outer faces of the sides of the Window-frame.

Vhat is claimed is- 1. In a device of the class described, the combination with a window, of an exterior tubular casing provided at its inner side with a vertical opening and havingr a laterally-projecting ange secured to the window-frame, a spring)r housed Within-the tubular casing and secured at its upper end to the top of the Window-frame, and means for connecting,r the upper sash With the spring, substantially as described.

2. In a device of the class described, the combination with a Window, of a spring connected with the upper sash, devices arranged at intervals on the Window-frame and on the lower sash, and cords connected With the top of the Window-frame and with the top of the upper sash and adapted to engage the said devices, substantially as described.

3. In a device of the class described, the combination with a window having sashes, of vertically-disposed couuterbalancing-springs connected with the sashes, and the combined guides consisting of tubular casings mounted on the exterior of the window and arranged to exclude the air and receiving the counterbalancing-springs, substantially as described.

In. testimony that I claim the foregrlgoine,r as my own I have hereto aix'ed my signature in the presence of two Witnesses.

GEORGE W. DURANT.
